Renesas M32C Single-chip 16/32-bit cmos microcomputer Datasheet

To our customers,
Old Company Name in Catalogs and Other Documents
On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology
Corporation, and Renesas Electronics Corporation took over all the business of both
companies. Therefore, although the old company name remains in this document, it is a valid
Renesas Electronics document. We appreciate your understanding.

SINGLE-CHIP 16/32-BIT CMOS MICROCOMPUTER
REJ03B0031-0100Z
Rev.1.00
Jun. 01, 2004
1. Overview
The M32C/81 group microcomputer is a single-chip control unit that utilizes high-performance silicon gate
CMOS technology with the M32C/80 series CPU core. The M32C/81 group is available in 144-pin and 100pin plastic molded LQFP/QFP packages.
With a 16-Mbyte address space, this microcomputer combines advanced instruction manipulation capabilities to process complex instructions by less bytes and execute instructions at higher speed.
It incorporates a multiplier and DMAC adequate for office automation, communication devices and industrial
equipments and other high-speed processing applications.
1.1 Applications
Audio, cameras, office equipment, communications equipment, portable equipment, etc.

1. Overview
M32C/81 Group
1.2 Difference between the M32C/81 Group and the M32C/83 Group
The M32/C81 group microcomputer has less peripheral functions than the M32C/83 group
miccrocomputer. The intelligent I/O group 3 and the A/D1 converter are not provided in the M32C/81
group. Interrupt requests, and as a result interrupts, DMAC, and DMACII, caused by intelligent I/O group 3
are not available in the M32C/81 group. However, the A/D1 conversion interrupt is generated in place of the
A/D0 conversion interrupt when input voltage applied to AN00 to AN07, AN20 to AN27, AN150 to AN157 pins
are converted.

2.1 General Registers
2.1.1 Data Registers (R0, R1, R2 and R3)
R0, R1, R2 and R3 are 16-bit registers for transfer, arithmetic and logic operations. R0 and R1 can be
split into high-order bits (R0H) and low-order bits (R0L) to be used separately as 8-bit data registers.
R0 can be combined with R2 to be used as a 32-bit data register (R2R0). The same applies to R3R1.
2.1.2 Address Registers (A0 and A1)
A0 and A1 are 24-bit registers for A0-/A1-indirect addressing, A0-/A1-relative addressing, transfer, arithmetic and logic operations.
2.1.3 Static Base Register (SB)
SB is a 24-bit register for SB-relative addressing.
2.1.4 Frame Base Register (FB)
FB is a 24-bit register for FB-relative addressing.
2.1.5 Program Counter (PC)
PC is 24 bits wide. It indicates an address of an instruction to be executed.
2.1.6 Interrupt Table Register (INTB)
INTB is a 24-bit register indicating a starting address of an interrupt vector table.
2.1.7 User Stack Pointer (USP), Interrupt Stack Pointer (ISP)
USP and ISP as the stack pointer are 24 bits wide. The U flag can switch USP to ISP and vice versa.
Refer to "2.1.8 Flag Register (FLG)" about the U flag. Set USP and ISP to even addresses to execute an
interrupt sequence efficiently.
2.1.8 Flag Register (FLG)
FLG is a 16-bit register indicating a CPU state.
2.1.8.1 Carry Flag (C)
The C flag indicates whether carry or borrow occurs after an instruction is executed.
2.1.8.2 Debug Flag (D)
The D flag is for debug only. Set to "0".
2.1.8.3 Zero Flag (Z)
The Z flag is set to "1" when the value of zero is obtained from an arithmetic calculation; otherwise "0".
2.1.8.4 Sign Flag (S)
The S flag is set to "1" when a negative value is obtained from an arithmetic calculation; otherwise "0".

2.1.8.5 Register Bank Select Flag (B)
The register bank 0 is selected when the B flag is set to "0". The register bank 1 is selected when this
flag is set to "1".
2.1.8.6 Overflow Flag (O)
The O flag is set to "1" when a result of an arithmetic operation overflows; otherwise "0".
2.1.8.7 Interrupt Enable Flag (I)
The I flag enables a maskable interrupt.
An interrupt is disabled when the I flag is set to "0" and is enabled when the I flag is set to "1". The I
flag is set to "0" when an interrupt is acknowledged.
2.1.8.8 Stack Pointer Select Flag (U)
ISP is selected when the U flag is set to "0". USP is selected when this flag is set to "1".
The U flag is set to "0" when a hardware interrupt is acknowledged or the INT instruction of software
interrupt numbers 0 to 31 is executed.
2.1.8.9 Processor Interrupt Priority Level (IPL)
IPL is 3 bits wide. It assigns an interrupt priority levels from level 0 to level 7.
If a requested interrupt has a greater priority than IPL, the interrupt is enabled.
2.1.8.10 Reserved Space
When writing to the reserved space, set to "0". When read, its content is indeterminate.
2.2 High-Speed Interrupt Registers
Registers associated with the high-speed interrupt are as follows.
- Flag save register (SVF)
- PC save register (SVP)
- Vector register (VCT)
2.3 DMAC-associated Registers
Registers associated with DMAC are as follows.
- DMA mode register (DMD0, DMD1)
- DMA transfer count register (DCT0, DCT1)
- DMA transfer count reload register (DRC0, DRC1)
- DMA memory address register (DMA0, DMA1)
- DMA SFR address register (DSA0, DSA1)
- DMA memory address reload register (DRA0, DRA1)

3. Memory
Figure 3.1 shows a memory map of the M32C/81 group.
M32C/81 provides 16-Mbyte address space from addresses 00000016 to FFFFFF16.
The internal ROM is allocated in lower addresses beginning with address FFFFFF16. For example, a 64Kbyte internal ROM is allocated in addresses FF000016 to FFFFFF16.
The fixed interrupt vectors are allocated in addresses FFFFDC16 to FFFFFF16. It stores the starting address of each interrupt routine.
The internal RAM is allocated in higher addresses beginning with address 00040016. For example, a 10Kbyte internal RAM is allocated in addresses 00040016 to 002BFF16. Besides storing data, it becomes
stacks when the subroutine is called or an interrupt is acknowleged.
The SFR is allocated in addresses 00000016 to 0003FF16. The control registers for peripheral functions
such as I/O port, A/D conversion, serial I/O, timer are allocated here. All addresses, which have nothing
allocated within the SFR, are reserved space and cannot be accessed by users.
The special page vectors are allocated in addresses FFFE0016 to FFFFDB16. It is used for the JMPS
instruction and JSRS instruction. Refer to the Renesas publication Software Manual for details.
In memory expansion mode and microprocessor mode, some space are reserved and cannot be accessed
by users.
